I sent a general inquiry email about another question but here was Dave's response.
"Dustin, thanks for the inquiry. We will not shoot super steel this month. I will add you to our match notification list. Your 2 15 round magazines will be adequate. 100 rounds are required to complete 1 relay(4 stages). Probably should plan on approx 130, no one had ever hit 100 of 100 at our steel match. A holster is a must and 2 mag pouches will be adequate. I'll provide more info as I am peeking on my iPhone. Dave"
